SUMMARY

This invention is related to fused benzeneoxyacetic acid derivatives.

BACKGROUND OF THE INVENTION

PGl₂ is a physiologically active natural substance having the following structural formula, which is biosynthesized from PGH₂ in the metabolic process in vivo called arachidonate cascade. ##STR3## (see Nature, 263, 663(1976), Prostaglandins, 12, 685(1976), ibid, 12, 915(1976), ibid, 13, 375(1977) and Chemical and Engineering News, Dec. 20, 17(1976).

PGl₂ has been confirmed to possess not only a very strong inhibitory activity on blood platelet aggregation but a dissociative activity on blood platelet aggregation, an inhibitory activity on blood platelet adhesion, a vasodilating activity, an inhibitory activity on gastric acid secretion etc. Therefore, it has been considered that PGl₂ is useful for the prevention and/or the treatment for thrombosis, arteriosclerosis, ischemic heart diseases, gastric ulcer, hypertension etc. But its application for pharmaceuticals is limited because of its chemical instability and difficulty of separation of the actions according to purpose. Accordingly, various PGl₂ derivatives have been synthesized and many researches have been carried out for the maintenance and the separation of the actions. However, we have not necessarily satisfactory results yet.

Recently, in order to solve two problems above described, the research for PGl₂ receptor agonists which have a new-typed skeleton and may be useful for the treatment of or for the prevention of the above diseases, in view of PGl₂ receptor level, has been carried out.

RELATED ARTS

it has been reported in the literatures, that the following compounds not having the PGl₂ skeleton are PGl₂ receptor agonists which bind to a PGl₂ receptor and inhibit blood platelet aggregation: ##STR4## (see Brit. J. Pharmacol., 76, 423(1982), ibid, 84, 595(1985), and the Japanese Patent Kohyo No. 55-501098), ##STR5## (see Brit. J. Pharmacol., 76,423(1982), ibid, 84, 595(1985), and the Japanese Patent Kohyo No. 57-501127), and ##STR6## (see Brit. J. Pharmacol., 102, 251-266(1991) and the West German Patent Publication No. 3,504,677).

PURPOSE OF THE INVENTION

Energetic investigations have been carried out in order to discover new PGl₂ receptor agonists having a skeleton in chemical structure different from the compounds mentioned above, the present inventors have found that a kind of fused benzeneoxyacetic acid-derivatives has an activity on binding to PGl₂ receptor and an inhibitory activity on blood platelet aggregation, and have accomplished the present invention.

The fused benzeneoxyacetic acid derivatives of the formula (I), of the present invention are quite novel, and it is not easy to predict from the above compounds already known as PGl₂ receptor agonist, that the compounds of the present invention have an activity of PGl₂ receptor agonist.

Pharmacological Activities

It has been confirmed that the compounds of the present invention of the formula (I) possess an agonistic activity on PGl₂ receptor by the following experimental results.

i) Inhibitory activity on binding of ³ H-iloprost to PGl₂ receptor on human blood platelet membrane fraction

Method

50 mM Tris-HCl buffer (pH 7.4) containing 15 mM MgCl₂, 5 mM EDTA and 10 nM [³ H]-iloprost were used as reaction medium. To 0.2 ml of the reaction medium, human blood platelet membrane fraction (0.3 mg protein) was added with or without a test compound. The mixture was incubated at 24° C. for 30 min. After incubation, 4 ml of ice-cold 10 mM Tris-HCl buffer (pH 7.4) was added to the reaction mixture, and filtered through Whatman GF/B glass fiber filter, and washed 4 times with 4 ml of ice-cold 10 mM Tris-HCl buffer (pH 7.4) to separate bound and free [³ H]-iloprost. After washing, the filter was dried and radioactivity was counted. Non-specific binding was obtained by performing parallel binding experiments in the presence of 10 μM non-labelled iloprost. Specific binding was calculated by subtracting the non-specific binding from the total binding.

The inhibitory effect of test compound was calculated from the following equation.

    The percentage of inhibition (%)=100-(B.sub.1 /B.sub.0 ×100)

B₁ : specific [³ H]-iloprost binding in presence of test compound

B₀ : specific [³ H]-iloprost binding in absence of test compound
